# HSU5N25

**HUASHUO** · MOSFETs · TO-252

HSU5N25 from HUASHUO, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate; the gate-source voltage is rated at ±20 V maximum, with a gate threshold of 1 V min to 3 V max at ID=250uA. |
| 2 | D | passive | Drain, also the exposed tab; the drain-source breakdown voltage is 250 V min, and the continuous drain current is 5 A at TC=25℃ with VGS=10V. |
| 3 | S | passive | Source; the continuous source (body diode) current is 5 A max, and the pulsed source current is 16 A max. |

## CAD (KiCad official)

- Symbol: `HSU5N25`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `hsu5n25-etched.step` / `hsu5n25-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hsu5n25.step` / `hsu5n25.glb` are the bare package body.
